Income against housing costs since 2015–2019

2015–2019 and 2020–2024 American Community Survey 5-year estimates
	2015–2019	2020–2024	Amount of change	Verdict
Median household income	$99,083 (±$4,549)	$108,281 (±$6,624)	+9.3%	Down after inflation
Median gross rent	$2,071 (±$106)	$2,521 (±$121)	+21.7%	No measurable change after inflation
Median home value	$664,400 (±$9,871)	$902,200 (±$17,619)	+35.8%	Up after inflation

The Census Bureau publishes 2015–2019 dollars in 2019 dollars and 2020–2024 dollars in 2024 dollars.

Prices (the CPI-U, US Bureau of Labor Statistics) rose 22.7% between 2019 and 2024, so a dollar figure’s verdict compares the two after raising the earlier one by that much, using the Census Bureau’s test for a difference.

The two periods do not overlap, as the Census Bureau recommends for 5-year estimates.
